Commodity Code
Description

Overview

Chapter 33 of the Harmonized Tariff Schedule of the United States (HTSUS) encompasses a wide array of aromatic substances and finished products. Heading 3301 specifically details the classification of essential oils and related resinous materials. This category covers volatile oils extracted from plant sources, including their concretes and absolutes, which are concentrated forms obtained through specific extraction processes. Resinoids, oleoresins, and terpenic by-products also fall under this heading, representing further refined or residual components derived from natural aromatic materials.

Unlike its sibling categories in Chapter 01, which deal with live animals, HTS 3301 focuses exclusively on chemical constituents and preparations derived from plants for their aromatic properties. It is crucial to distinguish these raw or semi-processed aromatic materials from finished perfumery, cosmetic, or toilet preparations that would be classified under later headings within Chapter 33. The key differentiator here is the nature of the product: Heading 3301 covers the fundamental aromatic essences and their immediate derivatives, rather than formulated end-use consumer goods.

The subcategories within 3301 provide for a more granular classification based on the source and type of the aromatic material. Subdivisions often differentiate between essential oils derived from citrus fruits and those from other botanical origins. Additionally, specific provisions exist for resinoids, which are obtained by solvent extraction and are typically solid or semi-solid. The "Other" subcategory serves to capture any remaining products within the scope of heading 3301 that are not specifically enumerated elsewhere, such as aqueous distillates or solutions of essential oils.
